Several high quality seafloor bottom maps are now available for consortium members and others interested in the seafloor observatory project. The maps were generated by C+C Technology Survey Services on May 3, 2005 using a Hugin 3000 AUV equipped with multibeam swath bathymetry, side-scan sonar, and chirp sub-bottom profiler. Easily downloadable subbottom profiles are also available below.

A base map for the seafloor observatory - 6.1 mb pdf (showing the MMS restricted zone and all sampling and installation locations)

Color-Shaded Bathymetric Map - 3.9 mb pdf

Color-Shaded Bathymetric Picture 21 mb tif (this tif file has no contour lines but affords an unobscured view of the seafloor topography, the file is large at approximately 20 megabytes)

The scale of the chirp lines is set to limit vertical exaggeration to 3:1 which results in rather long lines. The profiles are sized to plot on 24x46 inch paper, however, one should be able to zoom in on areas of interest and crop the image for desk top printing. Some quality of the image is lost in translating the data to picture format. The quality of these PDFs is good for general use. SEGY files of the data are available upon request.
